Didnt know what php is (unknown on Amiga ;). Ok, its not a php problem.
And not a FreeType2 problem. Must be a GD problem since php uses gd to
call FreeType2. Looked into the GD source code and found that:

----8<----
  for (n = 0; n < a->face->num_charmaps; n++)
    {
      charmap = a->face->charmaps[n];
      platform = charmap->platform_id;
      encoding = charmap->encoding_id;
      if ((platform == 3 && encoding == 1)      /* Windows Unicode */
          || (platform == 3 && encoding == 0)   /* Windows Symbol */
          || (platform == 2 && encoding == 1)   /* ISO Unicode */
          || (platform == 0))
        {                       /* Apple Unicode */
          a->have_char_map_unicode = 1;
          found = charmap;
----8<----

So it would work if GD would not forget to tell FreeType2 to use the
charmap it found... Send the following patch to the GD developers and
wait for a new GD version:
